A novel adsorbent of chitosan immobilization of β-cyclodextrin （CS-CD） was prepared by the reaction of β-cyclodextrin （β-CD） with the intermediate which was the hydrolysate of epichlorlhydrin reacted with Schiff base chitosan in sodium hydroxide solution. Its structure was confirmed by infrared spectra analysis（IR）, X-ray diffraction analysis（XRD） . The apparent amount of grafting of CS-CD is 25.8 μmol·g -1 . The adsorption property of CS-CD for paradioxybenzene was studied. The experimental results showed that the new adsorbent exerted adsorption upon the carefully chosen target. The highest saturated capacity of paradioxybenzene of CS-CD is 469.82 μmol·g -1 . β-环糊精 壳聚糖 固载 吸附剂 β-cyclodextrin chitosan immobilization adsorbent O636.1 国家教育部高等学校博士学科点专项研究基金资助项目（2000048615） 2004-02-01 2021-04-01 2
